FORCE-FEED LUBRICATOR.

To all whom it may concern:

Be it known that I, HERBERT J. LEIGHTON, acitizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain newand useful Force-Feed Lubricator, of which the following is a specification.

This invention relates to force feed lubricators particularly adapted for motor vehicles or any other machines in which a lubricant is fed to a plurality of points, and has for its object a construction whereby the outlet passages of the lubricator are provided in a very simple and economical man ner. The invention consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views. V

Figure 1 is a plan view of a lubricator embodying my invention, the container for the oil being removed and the driving shaft being shown in section.

Fig. 2 is a plan View of the base and plate thereon which forms the cover for the grooves therein, the plate being partly broken away. I

Fig. 3 is a sectional view, partly in elevation, on the plane of line A-A, Fig. 1.

Fig. 4 is an inverted plan view of the pump, a portion of its casing being broken away. l

Fig. 5 is a fragmentary sectional view taken on line AA., Fig. 1.

This lubricator comprises generally, a body including two parts, one a base and the other a member or plate lying on the base, one of said parts, here shown as the base, being formed with grooves in the face thereof'opposed to the other part, so that the latter covers the grooves, and one of said parts, here shown as the plate, being formed with perforations registering with portions of the grooves and forming ports through which the oil enters the grooves, and a pump for forcing the oil through said perforations and the grooves.

1 designates the base which is formed with a flat face having a plurality of grooves 2 including portions 3 which extend in radial directions from the inner ends of the grooves, and outer portions which com- Specification of Letters Patent.

municate with outlet ports 1, said inner ends serving as a cover for the grooves 2, the plate having itClI'CUlfll series of perforations 6, which register with the inner ends of the radial portions 3 of the grooves 2 and constitute ports through which the oil enters the grooves 2.

7 designates the pump casing, mounted on the plate 5 and secured in position in any suitable manner as by fastening members 8 passing vertically through a base flange 9 on the pump casing and through openings 10' in the plate and alined openings 11 in the base 1.

The movable parts of the pump in this form of my invention, include a pair of intermeshing gears 12, 13 engaging, on like sides as their lower sides, with the plate 5, the gear 13 being connected in any suitable manner to a driving shaft by a shaft section 1 1 journaled in a vertical bearing 15 in the casing 7 the shaft section having means at its upper end for connection to the driving shaft.

The gear 13 is formed with a transverse delivery passage 16 therethrough arranged to come successively into alinement with the perforations 6, in order to deliver the lubricant successively to the perforations 6, so that individual. impulses are imparted to the oil in the grooves 2.

The gear 13 is provided on its upper face with. an annular groove 17 into which grooves 17 the delivery passage 16 opens. The'entrance for the lubricant into the casing 7 is located at 18 an one side of the point at which the gears mesh and the compression chamber 19 is located on the other side of said point, the casing being formed with a connection between the chamber 19 and the groove 17 20 is thewall of a container mounted on the base and held in position by fastening members extending through alined openings 21, 22 and 23 in the container, the plate 5 and the base 1.. The container is usually bolted to the crank casing of the engine and is in communication with the crank casing in order to receive oil therefrom, the oil entering the container through the opening in the top of the container.

The ports 4 are preferably arranged in one side edge of the base, and pipes lead therefrom to the points to be lubricated.

Owing to the base 1 with the grooves therein and the plate 5. covering the grooves and having ports opening into the grooves, expensive machining and boring of the base is eliminated, and the base 1 can be die cast of a comparatively soft metal with the grooves therein and the plate 5 formed of a harder metal as brass capable of standing the wearof the movable partsof the pump,

What I claim is:

1. A force feed lubricator comprising a body including a base formed with grooves in one face thereof, a plate mounted on the base and covering the grooves and formed with perforations communicating with portions of the-grooves and constituting ports therefor, a pump casing mounted on the plate and movable parts within the casing for forcing the oil into, the grooves through the ports, said movable parts engaging the,

plate, substantially as and for the purpose specified. I

2. A forcev feed lubricator comprising a body including a base formed with grooves in one face thereof, a plate overlying said base and covering the grooves, the plate being formed with a series of perforations arranged to come into alinement respectively with portions of said grooves and constituting ports, a pump casing mounted above the plate, and movable parts located in the casing and including a distributer having a delivery passage arranged to come successively intoalinement with said, ports, substantially as and for the purpose set forth.

3. A force feed lubricator comprising a body including a base formed with a'series of grooves in one face thereof, the. inner ends of which grooves .are. arranged in a circular series, a, plate overlying the base and covering the grooves, the plate being formed with perforations in alinement with the inner ends of the grooves, theperforations constituting a circular series of inletports for the grooves, a container mounted above the base and the plate, and a pump mounted on the plate within the container for forcing oil through the perforations, substantially as and for the. purpose described.

4. A force feed lubricator comprising a body including a base formed with grooves in one face thereof and with a series of outlet ports, the grooves communicating with the ports, a plate mounted on the base, and coveringthe grooves and having ports for eating at their outer ends with the outlet ports, a plate mounted on the base and forming a cover for the grooves, the plate being formed with a circular series of perforations alined with the inner ends of the grooves, a pump casing mounted on the plate, and movable parts located 1n the casing and including a rotary distributer en gaging the plate and havinga delivery passage arranged to come successively into alinement with the perforations of the plate, substantially as and for the "purpose. set; forth.

6. A force feed lubricator comprising a body including two parts, one a base and the other a plate lying on the base, one of said parts being formed with grooves in the face thereof opposed to the other of said parts, and one of said parts being formed with perforations opening'into the grooves, and means for forcing the oil through the perforations and into the grooves, substantially as and for the purpose specified.

7. A force feed lubricator comprising a body including two parts, one a base and the other a plate lying on the base, one of said parts being formed with grooves in the face thereof opposed to the other of said parts, and the plate being formed with perforations opening into the grooves, anda pump mounted onthe plate and including a movable part for "forcingthe oil through the perforations, said movable part engag ng the plate, substantially as and for the purpose set forth. i

8. A force feed lubricator comprising a body including two parts, one a. base'and the other a plate lying on the base, one of said parts being formed with grooves in the face thereof opposed to the other ofsaid parts, and the plate being formed with a circular series of perforations opening into the. grooves respectively, and a pump mounted on the plate for forcing'oil through the perforations, substantially as and for the purpose'specified.

In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and State of New York, this 5th day of December, 1916.
